We have reviewed the Sony wireless headphones over a year. Noteworthy is the range, the comfort, the design. The thing is with us a constant Begeleiter when the loud music to disturb with the housework or barbecuing anyone. The 5.1 or 7.1 playback is not compared to the reference system and the home it can not, because of the maturity and reflections of the sound waves. The sound affects laboratory liable (rauschlos). The sending you is a matter of taste. But the spatial impression is absolutely OK.
